I'm also having a similar problem, though when my nexus 7 completely dies from the battery I plug in and right away power back up and when it comes to the home screen with 0-1% charge it right away powers down. I tried leaving it off while pluged in let it charge for 5 mins and then power back up again till I see it have a minimum amount of charge, it seems to work not sure if its ROM or kernel related, I'll keep an eye on it.

There's a helpful article that seems to help other nexus 7 users, hope this helps

I have the same problem with my nexus 7 3g.
Factory reset does not help.
Finally open the back cover (quite easy) and found that the battery cable connector is loose. So I tightened and my tablet is well again.
Hope this help.

Yeah what worked for me was to also unplug my battery. Seemed to correct itself after that. Mine would shut off showing a charge of 60%.

Does the back just unsnap like a regular battery door?

I have issues sometimes. Like the other night it charged all night and when I woke up it was fine, turn off the alarm on it and had breakfast. Came back and it wouldn't come on. Tried all I could without taking it apart. Ended up removing the back cover, unplugging the battery for ten seconds and then it worked fine. Battery was at 100% once it booted up.

Use your fingernail to get between it and the chassis. It pops off pretty easy. Just be careful. I'm sure YouTube has a few videos showing it.

Hi.. I Have the same model and I had the same problem...

I made the turn off method (https://plus.google.com/+DerekRoss/posts/563EVVEPMDS) and did not work...
I rooted my Nexus to calibrate the Battery (http://forum.xda-developers.com/show....php?t=1838429) and did not work.

But the in my case the most simple solution works : Unplug /plug the Battery (http://productforums.google.com/foru...g/ovuWYHUytZ0J).

Show this video about how to do it:
